Help‼️ Prom prep!!!🌺✨💋

Hi guys! So I’m going to prom with this guy I really really like so I wanna look extra good. I’m going for a light Madison Beer look and I want to get a primer and setting spray that will keep my makeup looking amazing all night but I have no idea where to start any recommendations?? And if you guys have any other tips, tricks, or products to recommend that would be amazing too!😘
